Efficient Effluent Treatment Plant

Abstract: A  combined  process  for  treatment  of  effluents  using biological treatment  and electro-oxidation  wherein  the effluent being  first  partially decolorized by adding  the enzymes;   Laccase (2%), Glucose oxidase (2%), Pectinase (4%) and catalase (4%)to the effluent, at 37⁰C & pH 5.5 for a period of 10 minutes; in 1:1 ratio; resulting effluent having reduced levels of factors; such factor being 78 % of Turbidity, 29 % of Total  hardness, 20 % of  Chemical oxygen demand, 36% of Silica, 56% of Chromium, 65% of Iron, and 82 % of color/hazen; the resultant effluent being further treated withan electro oxidationprocess for a further period of ten minutes; wherein the effluent is completely decolourised with COD reduction; wherein the Anode beingplatinum, titanium or graphite coated and cathode being Stainless steel; with 0.1 Ampere current for 12 cm surface area of (each) electrode and at the electrode distance of 2 cm for 100 ml effluentresulting in decolorized effluent with 9 % Total hardness, 97 % biological Oxygen demand, 34 % Chemical oxygen demand, 42 % silica, 73 % Chromium, 48 % iron and 98 % color/hazen; the entire process of decolorized effluent with no additional sludgeformation,being achieved in a 20 minute time frame; resulting in  removal of Turbidity to 85 %, total hardness to 36%, Biological oxygen demandto 96%, Chemical oxygen demand to 48%, Silica to 63%, Chromium to 88 %, Iron to 82 % and 98% color/hazen;leading to lower time lines,lower cost and a zero level discharge environmentally friendly process.
